Lick the frosting off…
Mmm… Microplastics
A wire brush. Handheld, not attached to an electric grinder or something like that.
Cheap wire brushes should be available in most hardware stores. I know that ours carries them in the paint section.
Remove the nozzle and hold it with pliers or something.
Blow on it really hard.
And then rub it for three wishes.
I just bought a new heating element when that happened to me.
I might go back with some acetone now after reading others’ comments.
Not for PLA
What type of filament is that?
Maybe try a heatgun to soften it. I’m not sure, might damage the plastic casing.
PLA
PLA basically doesn’t dissolve in any (readily available consumer-grade) solvents. Your best bet is going to be to take the entire unit as far apart as you can until it is metal only components, heat it with a heatgun to make the PLA soft/melt, and brush it all off with a brass cleaning brush.
OK, you’re gonna need some things:
A heat gun, A wire brush, Bandaids, A stiff drink
A SWAT team ready to mobilize, street level maps covering all of Florida, a pot of coffee, 12 Jammy Dodgers and a fez.
I heated up the nozzle separately in some boiling water and scraped off almost all of it. Then I put it back into the hot end and heated it up to 200 C, took it back out and q-tipped off a lot of the rest. There’s still some but I’m running a print right now and it’s working fine.
Hrrmm. Does it still print? Personally I’d go with hope it kind of burns off over time with normal use. Others may disagree…
That certainly is one way to make it immediately worse, and welcome a whole cavalcade of failures throughout the machine. 🫣
Microwave
Metal piece with many pointy pieces and neodymium magnets in a microwave? The sparks will damage the item and the oven. And won’t melt the plastic
